Abstract

A muffler is disclosed . In the muffler a throttling device which is controlled by the energy of the airflow to be muffled is provided in a pipe line of the airflow which needs to be muffled. The muffler is adjusted by itself according to random variety of the pulsing airflow , and can eliminate or reduce effectively the pulsation of the airflow and the related noise in the range of the low frequency and the middle frequency . The muffling effect of the muffler has no correlation with the volume of the muffler , and therefore the volume of the muffler can be reduced. <IMAGE>
